The 14-year-old Reno boy who was shot by a school district police officer underwent surgery after suffering a stroke at a local hospital where he”s recovering from the gunshot wound to his chest.

The teen”s lawyer, David Houston, said the teen was out of surgery Friday afternoon and taken to the intensive care unit at Renown Regional Medical Center where his condition is unknown.

Houston said earlier Friday the boy had been critical, but stable, and was showing signs of improvement before suffering “a major stroke.”

The boy”s father hired the prominent Reno attorney to defend his son against any potential criminal charges in connection with the shooting. Reno police say he was threatening other students with a knife and refused to drop the weapon before a school district police officer shot him in a courtyard.

2:15 p.m.

The lawyer for a 14-year-old boy who was shot by a school police officer in Reno says he had armed himself with a kitchen knife because he”d been bullied and beaten by upperclassmen.

David Houston told The Associated Press on Friday the emotionally distressed teen was trying to escape from a crowd of classmates who had gathered to capture video of a fight when the officer inexplicably shot him Wednesday.

Houston said the boy remains in critical condition with a gunshot wound, but is stable and improving.

He said videos posted online suggest none of the students felt threatened and most appeared shocked when the officer opened fire.

Houston told AP the boy was “trying to extricate himself from a situation that had become like spectators in the Roman coliseum.”
